As bystanders yelled at Stucker to leave him alone, McTamney turned blue and eventually stopped breathing. Some witnesses tried to perform CPR on him until paramedics arrived.

McTamney of Pennsylvania was taken to Morton Plant Hospital, where he died later that morning, police said.

An autopsy revealed McTamney's cause of death was asphyxiation. The manner of death was homicide, police said. The autopsy report was not available Wednesday.

"I have every confidence that justice will be served," said McTamney's wife, Colette, in an email to the Tampa Bay Times. "David was a very kind and caring man. He was a wonderful father to our two young children, and a great husband, son, uncle and friend. We have suffered a very tragic and senseless loss."

Stucker, of 514 N Madison Ave., was an independent contractor who had worked as a bouncer at Brown Boxer for about a year. Stucker had not been involved in any other altercations with patrons, said Brown Boxer owner Jay Thomas.

In Florida, Stucker has a string of arrests dating back to 1995, including convictions on charges of cocaine possession and battery, state records show.

McTamney did not have a criminal record in Florida or Pennsylvania, records show.

Stucker was booked into the Pinellas County Jail, where he remained Wednesday afternoon in lieu of $100,000 bail.
